CMS CSC(EMU) Data Concentrator Card (DCC)
DCC is a high speed data concentrator card at 2* GigaByte per second. DCC collects the CSC data from DDUs data at 10 * 640 MegaByte per second through custom backplane in FED crate, then sends data to main CMS DAQ at 2* 800 MegaByte per second by SLINK64, and local debug computer at 2* Gigabit per second through fiber gigabitethernet. It also receives TTC control signals and fan out to the FED crate. DCC is a 9Ux220mm slave VME board. It talks with VME controller (VME master in slot 1) through the P1 connector (A24D16).
